This species is known from two localities in southern Papua New Guinea: the Darai Plateau in Southern Highlands Province at 420m asl; Dark End Lumber in Gulf Province (Richards and Oliver, 2006). It probably occurs more widely, and a specimen from Kokoda in the Owen Stanley Range might refer to this species (Richards and Oliver, 2006).
Habitat and Ecology
This species has been found only in trees in primary rainforest where males call at night from branches high above the ground (Richards and Oliver, 2006). Its breeding requirements are unknown, though it possibly lays eggs in tree holes, and presumably breeds by larval development.
There is no information on its abundance, as it is a canopy species which is hard to find.
The habitat where the species is known to occur is reasonably well conserved. However, the species probably occurs more widely, and might be found in less well protected sites. It is probably dependent on intact rainforest.
Both known localities are in the Kikori Integrated Conservation and Development Project area (Richards and Oliver, 2006), where the habitat is conserved. Surveys are needed to determine its geographic distribution, ecological requirements, and conservation needs.
Richards and Oliver (2006) separated this species from Litoria graminea.
